hwmon: (ltc2945): add support for sense resistor

expand
|
This changeset adds support the sense resistor that can be connected on a board to computer current & power. The sense resistor is a parameter of the board. It should be configured in the driver via a device-tree / ACPI property, so that the proper current measurements can be done in the driver. Changelog v1 -> v2: * https://lore.kernel.org/linux-hwmon/20201106101825.30960-1-alexandru.ardelean@analog.com/ * reverted kstrotoull() -> kstrtoul() * added sanity check for resistor, to prevent crashing when DT provides zero value * add DT binding doc for ltc2945 Alexandru Ardelean (4): hwmon: (ltc2945): wrap regmap into an ltc2945_state struct docs: hwmon: (ltc2945): change type of val to ULL in ltc2945_val_to_reg() hwmon: (ltc2945): add support for sense resistor dt-bindings: hwmon: ltc2945: add device tree doc for ltc2945 .../bindings/hwmon/adi,ltc2945.yaml | 49 ++++++++++ drivers/hwmon/ltc2945.c | 89 +++++++++++-------- 2 files changed, 103 insertions(+), 35 deletions(-) create mode 100644 Documentation/devicetree/bindings/hwmon/adi,ltc2945.yaml
